Abstract
The effects of some environmental pollutants on the growth, chemical composition and physiological behaviour of wheat (cereal crop) and faba bean (legum crop) were studied in the expermental farm Faculty of Agriculture Menofyia University, during the two successive seasons of
1992 /1993 and 1993 /1994 to establish this study, two pot experments were coducted and the pollutants were irrigation with sewage effluent ei ther diluted or undiluted, drainage water and lead as a dominant heavy metals in the egyptian environment. Sewage effluent and drainage water were used in the irrigation, lead acetat was used as foliar spray at the con centraions of (0, 50, 100 .and 150 p.p.m).
Each of the prevausly mentioned treatments was repeated four times in
each season. The averages of the collected data were presented and dis
cussed.The obtained results indicated that :
A -Sewage effluent and drainage water
1- Sewage effluent at the rate of 100% had most harmfull effect on the ve getative growth of both faba bean and wheat plants, it reduced fresh and dry weight of roots and shoots for wheat and roots, stems and leaves for faba bean, and decreased the leaf area, plant height and number of leaves
for both crops compared with control plants. The rate of 50 % caused a
slightly decrease of fresh and dry weight of shoots and roots for wheat and roots, stems and leaves for faba bean, while it increased leaf area, number of leaves and plant height for wheat and decreased it for faba bean. Drain age water decreased fresh and dry weight of roots, stems and leaves for faba bean and wheat shoots, and increased fresh and dry weight of wheat roots after 45 and 60 days from planting and decreased it after 75 days , and increased the number of leaves, plant height and leaf area for wheat and decreased it for faba bean compared with control plants.
